LENTIS Mplus X: The neXt generation
of the world‘s unique multifocal Mplus-IOL-technology

Since the End of 2013 Oculentis offers with the LENTIS Mplus X an advanced and improved version of the previous Mplus model with optimised near vision.

Technical evolution of the optical mode of action

What makes the Mplus X-technology unique?
LENTIS Mplus X with „Additive Paraxial Asphericity“ (APA):
  • Enhanced far and near focus zones for better depth of focus and a balanced vision at all viewing distances
  • Outstanding visual performance in the entire intermediate vision field by adapted zone focusing
  • Easier neuronal image interpretation due to intelligent focal modulation for all light conditions
LENTIS Mplus X with „Surface Design Optimisation” (SDO):
  • Higher pupil independence and better reading through a new surface design of the near vision segment
  • Light efficiency > 95% by improved SML production technology
  • Significantly reduced photopic phenomena by homogeneous peripheral transition zone
Lentis Mplus vs Mplus X
Get off the Peaks, get into the Zone!
The ambition behind the Mplus modification and the objective of the new Mplus X is to achieve a general enhancement and extension of the depth of focus, not just an improvement of individual focal points. The unique and unmistakable defocus curve of the Mplus X visualises the following: Instead of being limited to the maximisation of so called “peaks” in the near, intermediate and far vision, the Mplus X maximises the total area under the defocus curve, which corresponds to the entire viewing zone.The result: genuine extension of the depth of focus at all distances!
Advantages of the new Mplus X-technology
  • Excellent visual acuity results for the complete near range
  • Very good visual acuity results for the complete intermediate range due to the extended depth of focus
  • Maximised light efficiency of > 95%
  • Natural contrast and colour perception
  • True 360° sharp optic edge
  • Proven HydroSmart-Acrylate

The binocular defocus graph of the LENTIS Mplus X confirms the outstanding visual acuity performance of this multifocal lens for all distances. In addition to the strong visual performance for the distance vision the chart shows, in particular the balanced visual results for the intermediate and near vision. No significant slopes in visual acuity between the individual visual distances exist. Furthermore, the area-of-focus metric is maximized and thus creating a balanced and natural vision.

The LENTIS Mplus X with 3.0 Addition is a complete solution guaranteeing balanced vision at any distance, but particularly at near range, without glasses. It offers patients the highest quality of life with best near vision.See also Shah S., Buckhurst PJ et al.
What do the professionals say about the LENTIS Mplus X?

“Just like the LENTIS Mplus, the LENTIS Mplus X IOL has excellent contrast sensitivity. Additionally, this new lens provides patients with significantly better intermediate vision and, on average, 1 more line of near visual acuity. In addition to the benefit of providing a wide range of functional vision, the Mplus X lens design addresses the minimal drawbacks of the first-generation design. Although it is not a trifocal lens, the results are probably better than what we can achieve with a trifocal.“Prof. Dr. Sunil Shah, MD, FRCOphth, FRCS(Ed), 02/2014.“Initial outcomes are marvelous, and the IOL provides very clear vision from far to near distances. Due to its design, the loss of light is minimal and, therefore, my patients do not complain about night driving problems or waxy vision. I acknowledge the advantage of the LENTIS Mplus X IOL and, therefore, at the moment it is my first choice among multifocal IOLs.”

LENTIS Mplus success story: Convincing clinical results!
5 years on the market, about 250,000 implants worldwide, peerless to date: The unique multifocal IOL technology of the Mplus series has convinced doctors and patients with above average visual acuity results. In the following we will present several of the clinical results obtained so far.pdf logo  Data Sheet LENTIS Mplus LS-313 MF30
Prof. Dr. Sunil Shah, Midland Eye, Solihull West Midlands, UK
Excellent contrast sensitivity resultsThe question raised by Prof. Sunil Shah‘s presented graphics focuses on contrast sensitivity. The charts compare the contrast sensitivity of monofocal IOLs with those of the rotationally asymmetric LENTIS Mplus MIOLs. Conventional, rotationally symmetric multifocal IOLs are known for their problems with contrast sensitivity due to the technically induced high loss of light. In comparison, the sector shaped Mplus-MIOL, with its very good light efficiency, shows a naturally high contrast sensitivity equal to those of monofocal IOLs.

Prof. Dr. Jan Venter, Medical Director of Optical Express, London, UK
Visual acuity results of almost 10,000 LENTIS Mpuls IOLs clinical evaluated: in a large comparative study, carried out by Professor Jan Venter between November 2009 and September 2011, 9,366 eyes of 4,683 patients were treated with LENTIS Mplus intraocular lenses. During a 6-month follow-up study, the near, intermediate and distance visual acuity results of 4,240 LENTIS LS-312 MF30 IOL models (C-loop design) and 5,126 LENTIS LS-313 MF30 IOL models (plate haptic design) were compared with each other, before and after surgery, and evaluated. The visual acuity of the patients was excellent for all distances for both lens models.

In addition, a patient survey was carried out. 98% of the patients were happy with the results after surgery and 86% had no problems reading very small print.Almost all patients would therefore unreservedly recommend the LENTIS Mplus!

The subjective defocus graph of the LENTIS Mplus, provided by Dr. Pierre-Jean Pisella, shows the above-average intermediate visual acuity of this rotationally asymmetric multifocal IOL compared to two concentric ring MIOL types currently available on the market.

Far visual acuity: All investigated MIOL show very good visual acuity results for the far distance range and show no significant differences.Near visual acuity: The optimally usable near vision distance differs due to the actual addition of the tested MIOLs. At the average reading distance of 40 cm (defocus at -2.5D) all evaluated MIOLs achieve a very good near visual acuity of approximately 0.1 logMAR. The diffractive MIOL (type B) provides sharp vision at very short distances, e.g. at 33 cm, but with a greatly reduced visual acuity in the entire intermediate range. The performance of the concentric ring refractive MIOL (type A) is highly dependent on the existing light conditions and the resulting pupil size. A longer reading time is only possible under daylight conditions due to the usable areas of this IOL optic and the physiological miosis.Intermediate visual acuity: Most of every days visual tasks are mastered, however, in the so-called intermediate region, which is why the intermediate visual performance of a MIOL is of a particularly high importance. At the viewing distance of 60 cm to 2 m almost all daily activities take place, such as computer and office work, driving a car, shopping at the supermarket or watching television. Therefore, a modern MIOL should offer an excellent intermediate vision to ensure that patients’ needs of glasses are substantially reduced.The comparative study shows clearly that only the LENTIS Mplus offers very good intermediate visual acuity over this important visual range. These results are significantly better than these achieved by the concentric rings MIOLs.

Conclusion: With the LENTIS Mplus multifocal IOL ophthalmologists can offer their patients a balanced intraocular MIOL-solution: It guarantees a high level of spectacle independence in the distance range, throughout the whole intermediate range and in a reasonable reading distance of 40 cm.

Prof. Dr. Gerd U. Auffarth, University Ophthalmology Clinic Heidelberg, Germany
A multi-centre study under the management of Prof. Dr. Gerd U. Auffarth die LENTIS Mpuls were implanted in 134 eyes of 79 patients with an average age of 68 ± 12 years, confirmed that the MIOLs produced very good functional results with a very high patient satisfaction rate of 95%.The IOLs were implanted both unilaterally and bilaterally without any complications. The mean IOL strength was 21.00 ± 2.01D. Twelve months after surgery, a best-corrected distance visual acuity level of -0.03 logMAR was measured. The uncorrected near visual acuity level came to 0.08 logMAR. This corresponds to, on average, a distance visual acuity level of 1.10 and a near visual acuity level of 0.83.

What do the professionals say about the LENTIS Mplus?

“I think that what we have to remember is that diffractive multifocal lenses have been available for 20 years, with a typical energy loss of approximately 20%. If we compare this to 7% (with the Mplus), the difference is not the 14% or 15% we showed in our study—the difference is a 66% less loss of energy. I think if you look at it from this perspective, then you can understand the big difference between this and other multifocal IOLs.”Prof. Dr. Gerd U. Auffarth, MD, PhD in LENTIS Mplus and LENTIS Mplus Toric – Advanced multifocal IOL technology for the treatment of presbyopia, astigmatism, and cataract, supplement to CRST Europe 02/2012.“There are 40 Optical Express clinics in the United Kingdom, and each clinic performs laser vision correction as well as refractive lens exchange/cataract procedures. […] Ninety-five percent of all patients who are treated at one of our centers will receive the Mplus. […] We have so much confidence in the Mplus that the surgeon sees the patient on the day of surgery for the first time.“

LENTIS: Large selection of IOL designs

Oculentis offers a variety of IOL designs. Choose between (a)spherical, 1-piece or 3-piece IOL, IOL with or without violet light filtering technology
Aspherical intraocular lenses

The imaging quality of intraocular lenses (IOL) is one of the key factors to ensure an optimal vision for patients after a cataract surgery.

Aspherical LENTIS IOL are characterized by an aberration corrective surface structure. Basis for their design is not as usual a purely spherical cornea but a slightly aspherical cornea (anticipated in the human eye). Studies have shown that the human cornea shows asphericity in respect of the statistical median. Due to this fact, Intraocular lenses, which take into account this aberration, lead to a better visual acuity and better image quality.

Lentis lenses
Figure: All aspherical LENTIS lenses are also available with violet light filter: LS-312Y and LS-313Y
 
Lentis lenses

LS-412Y:

Oculentis’ 3-piece aspheric IOL with violet light filter is by its overall diameter of 13.0 mm (optical diameter 6.0 mm) the perfect intraocular lens for the optimal sulcus fixation.

 

 

SML-Technology
All aspherical LENTIS lenses are manufactured in the sub-micron lathing process. The square-edge design and the superior surface quality of our HydroSmart Acrylic reduce the post-surgery-cataract formation and thus the post-treatment rate. A recent study conducted by the Berlin Eye Research Institute (BERI confirms the exceptionally sharp optic edges of the LENTIS IOL for a better PCO prophylaxis (Study as PDF-Download below). All LENTIS lenses show an excellent biocompatibility and high stability in the capsule bag.

 

Spherical intraocular lenses
All spherical lenses of Oculentis are manufactured with a state-of-the-art Sub-Micron Lathing technique. Thanks to this technology, the lenses do not require additional polishing after production and thus keep their square edges. This “square edge design“ as well as the excellent surface quality lead to a lower rate of secondary cataract formation and thus reduce the need for additional treatment.

Excursus about Asphericity

Spherical Intraocular Lenses

Spherical aberrations are an optical imaging error, which leads to impaired vision. External light rays are refracted more strongly than the more central rays (see figure). Therefore, not all light rays will focus on the macula (yellow spot or „point of sharpest vision“). This results in poor contrast sensitivity. Spherical intraocular lenses do not correct these aberrations.

Spheric

Aspherical LENTIS Intraocular Lenses

All aspherical LENTIS intraocular lenses correct these spherical aberrations. The aspherical lens surface focuses all the light rays correctly on the macula. Thereby an optimal image on the retina is created which leads to a very good contrast sensitivity for the patient. In turn twilight vision will be improved.
